Ruling on answering the telephone during prayer

Question:
Also, regarding this, you say: If a person is in prayer, is it not permissible to answer the telephone during prayer, meaning: picking up the receiver to let the caller know that the people of the house are present?

Answer:
No, it does no harm. Picking up the receiver and letting it wait is permissible. Pick up the receiver, but do not speak until you have finished your prayer, unless it is a voluntary prayer. In that case, there is no harm in breaking it off for a pressing need, if it is a voluntary prayer. There is no harm in breaking it off for a pressing need if he fears that the people on the telephone have a major matter, or if he knows that. Otherwise, he completes his prayer and then speaks. As for the obligatory prayer, no, he does not break it off. But he picks up the receiver so that the person on the line waits. Yes.
